SPECIFICATION forming part of Letters IPatent No. 615,267, datedDecember 6, 1898.

Application filed May 18, 1898. Serial No. 681,068. (No model.)

To aZZ whom itmay concern:

Be it known that I, AUGUST J. FRANK, a citizen of the United States,residing at Varsaw, in the county of Hancock and State of Illinois, haveinvented certain new and useful Improvements in Warming-Ovens for Oil orVapor Burning Stoves; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to improvements in oil or vapor burning stoves; andthe object is to provide a stove of this character with an independentwarming-oven for keeping edibles, plates, dishes, and the like at aproper temperature until required for use.

To this end the invention consists in certain features of constructionand combination of parts, as will'be hereinafter fully described andclaimed.

In the accompanying drawings I have illustrated my invention in the bestform now known to me, though various changes in the details might bemade within the skill of a good mechanic without departing from thespirit of the invention, as set forth in the claim at the end of thisspecification.

In the drawings, Figure 1 is a perspective view of an oil-stove, showingmy improved warming-oven in place. Fig. 2 is a top plan view, partly insection. Fig. 3 is a longitudinal vertical section of the oven, with thehood and burner shown in elevation.

1 denotes the oil-stove, 13 its burner, and

3 the warming-oven, removably supported on the bracket 4, which in turnis detachablysecured to the stove 1. This oven may be of any suitablesize and shape, and it is provided with the usual hinged door and ahorizontal shelf 5, which is formed with a series of orifices 6 6 andwith a hinged plate 6, as shown in dotted lines in Fig. 2, which may bethrown over the orifices 6 6 to close them or thrown back to open themand permit the passage of the heated air through them.

7 7 denote similar orifices in the top of the oven to serve as an outletfor the heated air, and they may be closed by a hinged plate 8.

drical burner 13 of the stove.

9 denotes a vertical flue (preferably ovalin cross-section to economizespace) fixed in the bottom of the oven and having its upper open endextending to within a short distance of the bottom of the shelf 5. Thelower end of this flue 9 extends through the bottom of the oven andterminates in an elbow 10, in the horizontal arm of which is adj ustablysecured a sliding hood 12, the outer end of which is concaved topartially encompass the cylin- The sliding hood 12 is provided with aradial non-conducting handle 14 for conveniently adjusting it withreference to the burner, so that more or less heated air will beconducted to the oven through the hot-air flue. The heated air as itescapes from the upper open end of the flue impinges directly on thebottom of the hot shelf, spreading under its entire surface, and thenpasses through the orifices 6 6 into the upper compartment, whence itescapes into the atmosphere through the orifices 7 7. When both of thevalve-plates 6 and 8 are open, a uniform temperature is maintained; butif the valve-plate 6 only be closed there is then no outlet for the heatproducts in the lower compartment and a constant degree of heat isattained, while the upper compartment can be maintained at a much lessdegree of heat by reason of the supply being cut off and the heated aircontained therein allowed to escape through the open valve-plate 8.

Having thus described my invention, what is claimed as new,and desiredto be secured by Letters Patent, is

The combination with the burner 13, of the oven 3, the flue 9communicating with said oven, and the hood 12 adj ustably secured to theouter end of said flue and adapted to be projected into and withdrawnfrom the path of the products of combustion generated by said burner,substantially as set forth.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

AUGUST J. FRANK.
